Bob,

I always have some portion of hives that lag with these symptoms, usually in the fall but also sometimes after almond pollination.  It seems to take a full 3-4 weeks of improved forage for the hives to recover.  It is not surprising to me that the symptoms have not cleared up yet.

If the hives are suffering enough that some are already dying, then I would take immediate action.  I would combine them, and when they begin to come out of their downward spiral I would requeen them all.  I have found that the power of requeening cannot be underestimated for hives that succumb to ailments like this.
